    I agree with all of these answers.
    Why 90 degrees I thought you had to use a protracter to measure the angle and I got 70 degrees ://

    5ii. Mine was 9o'clock as it had only moved through a 1/4 of a wave and was moving in the anti-clockwise direction. I got the same for G though? Thoughts?
    I got that it pointed to 3 o'clock

    It was phasor E not B?

    Balls, probably me that's wrong then. It was just at the end of the first crest wasn't it? And im sure the phasor started at the top of that crest?

    Pretty certain the first phasor was 3 o clock and the second phasor was in between 10 and 11 o clock. Can pretty much guarantee that

    Cant remember all the questions but I'll make a start and hopefully others will continue.

    1. Watts is js^-1 and force is kgms^-2
    2. Can't remember if it was BCBC OR CBCB

    feel free to disagree!
    On 2) I was an absolute idiot, thought you could only use each graph once, so I had like an A, a B and two c's (can't remember the order) so I changed one of the c's for d because I didn't know you could use it twice...

    What did people write for the CRO development question? I was a bit lost on that one, I kind of just rambled on about digitisation, data compression and transfer, and the incompatibility of analogue signals with modern day technology. Had no clue :P

    You just rewrite the last paragraph of the article and explain it.

    Any way, guess it's on to S1 and FP1 tomorrow, and the D1 on Thursday. Then partyyyyyy...until the UKCAT Exam I'm doing early August so revision for that starts July...The painful life of a medical applicant :'(

    I finish tomorrow, D1, OCR. But applying for maths at Cambridge is just as bad as a medical applicant e.g. STEP papers. Plus I'm applying for imperial, so ill do the MAT as well. Life isn't easy for all of us, not just medical applicants have it hard!

    I think there were two main things from the article so write then explain each one. 2+2

    4.7?


    Posted from TSR Mobile
    I got 4.32.

    It certainly wasn't 6!

    I got the base to be 0.94 (seconds) and the change to be 9.2 ms-1.

    What did people put for the effect of increasing the kinetic energy by a factor of 4 or whatever it was?

    Decreasing by 4 was the question.

    KE is proportional to v^2. Therefore velocity halves. If velocity halves, wavelength doubles.

    Kinetic energy is inversely proportional to wavelength squared. So rearranging the formula with kinetic energy reduced by a factor of 4 (i think it was reduced) should double wavelength.

    Dom has it; though I used a formula from A2 physics, sort of cheating haha

    It's Kinetic energy= h^2/2mW^2

    (w is wavelength as I don't know how to put greek letters)
